You can't frikken "git-r-dun" and just wire it up willy nilly. I suggest you take a look at the Conotour PID's and compare them to the Coil-on-plugs PID's from an LS, for example, before you start spouting out about crap you know nothing of, first!

PS - not to mention to firing strategy is tottally different too.



Maybe he means to wire two coils in series or parallel so that each pair acts like a channel of the current coil pack.
The only thing with that is what the impedance would be and how closely it would match the current coil pack. There is no way to know what the electrical characteristics of the spark would be without first calculating coil impedance.
Or couse someone could just wire it up and hope it fires....without burning out the coil driver in the pcm.

But for the sake of argument, lets say that ideally the two coils in series or in parallel would have approximately the same resistance as one of the single coils in the 3 coil pack....then I think it would fire okay and any codes in the pcm would correspond to 'both' coils.
THe only advantage would be the elimination of plug wires.
